I still say the difference between an Artifact mass producing Artifacts and creating an Artifact that can be used by more than one person at a time is quite large. The created items wouldn't have the special powers equivalent of tier actions that make an Artifact an Artifact. All the power would be held by the original Divine Artifact.
If Jester wanted to make a Divine Artifact that made weapons that changed depending on the owners domain, it wouldn't be game breaking. Each weapon wouldn't be a Divine Artifact itself.
I have to go for a little bit so I won't be able to respond right away.
Romans 8:31 What, then, shall we say in response to this? If God is for us, who can be against us?
1 Corinthians 13:1-3 If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but do not have love, I am nothing. If I give all I possess to the poor and give over my body to hardship that I may boast, but do not have love, I gain nothing.
